If the server responds with a temporary error status, you can use the smtp_fallback_relay feature to deliver mail elsewhere. http://www.postfix.org/postconf.5.html#smtp_fallback_relay If the server responds with a permanent error status, then you could change that with smtp_delivery_status_filter, but you do so at your own peril. http://www.postfix.org/postconf.5.html#smtp_delivery_status_filter Wietse
